    Abstract: A prosthetic heart valve can include a radially collapsible and expandable annular frame having a plurality of struts defining openings. The prosthetic heart valve can further include a plurality of leaflets that regulate the flow of blood through the frame. The prosthetic heart valve can also include a sealing member mounted on the frame and having an inner layer and an outer layer. At least the outer layer is mounted on the outside of the frame, and the inner layer covers at least the openings in the frame between adjacent cusp portions of adjacent leaflets and the inner layer does not cover one or more openings in the frame at locations facing the outflow surfaces of the leaflets to permit retrograde blood to flow through the one or more uncovered openings in the frame and into space between the outer layer and the frame.

    Abstract: An implantable prosthetic valve that is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration includes an annular frame including a plurality of angled strut members, and a skirt member secured to the frame. The skirt member includes a plurality of extension portions wrapped around at least one strut member adjacent the extension portions. The prosthetic valve further includes a cord member threaded through at least a portion of the plurality of extension portions to secure the skirt member to the at least one strut member.

    Abstract: In one embodiment, a prosthetic valve can comprise a radially expandable and compressible frame, which can include a plurality of struts which are pivotally joined together without requiring individual rivets. In some embodiments, the struts are interwoven, and can be joined using integral hinges formed in the struts, such as by performing alternate cuts on the struts, bending the struts to form stopper tabs adjacent to joints and/or drilling holes in the struts to facilitate interconnecting struts at joints, or otherwise forming integral hinges and corresponding holes at junction points between the struts. In another embodiment, the frame comprises a plurality of inner struts and outer struts which are connected by a plurality of chains of interconnected rivets, avoiding the need to provide individual rivets at each junction between struts. In still another embodiment, separate hinges are provided to interconnect the struts. In still another embodiment, separate flanged rivets are provided to connect the struts.

    Abstract: A prosthetic heart valve can include a radially expandable and compressible frame having an inflow end portion and an outflow end portion, the frame comprising a plurality of struts defining openings between them. The prosthetic valve can further include a valvular structure comprising a plurality of leaflets, each leaflet comprising a main body, opposing tabs on opposite sides of the main body, a coaptation edge portion, and a cusp edge portion. Each tab can be paired with an adjacent tab of an adjacent leaflet to form a plurality of commissures that are fixed relative to the frame, and each leaflet can have opposing edge portions between the opposing tabs and the cusp edge portion that are unattached to the frame, each unattached edge portion defining a gap that extends radially into the main body of the leaflet.

    Abstract: A prosthetic heart valve can include a radially expandable and compressible frame having an inflow end, an outflow end, and a plurality of struts. The prosthetic valve can further include a valvular structure comprising a plurality of leaflets, each leaflet comprising a coaptation edge portion and a cusp edge portion. The cusp edge portion of each leaflet can be folded toward the outflow end of the frame along a bending axis and a reinforcing member extends along an outflow surface of the cusp edge portion along the bending axis. The prosthetic heart valve can include a plurality of connecting skirts, each disposed between the cusp edge portion of an adjacent leaflet and the frame. First stitching secures the reinforcing member and the connecting skirts to the cusp edge portions and second stitching secures the connecting skirts to selected struts of the frame.

    Abstract: In one embodiment, a method of assembling a prosthetic valve can comprise forming a radially expandable and compressible frame by pivotally joining together a plurality of struts without requiring individual rivets. In some embodiments, the frame is formed by interweaving the struts, which can be joined using integral hinges formed in the struts, such as by performing alternate cuts on the struts, bending the struts to form stopper tabs adjacent to joints and/or drilling holes in the struts to facilitate interconnecting struts at joints, or otherwise forming integral hinges and corresponding holes at junction points between the struts. In other embodiments, separate hinges are provided to interconnect the struts. In still other embodiments, separate flanged rivets are provided to connect the struts.
